Experimenting “Air and its properties” in the preparatory group
- Guys, do you know what air is? Where is the air? Who breathes the air? Is it possible to live without air? Take a breath, what did you inhale?- Guys, when we inhale air, our lungs fill with air. We can feel it with you. Place your hands on your chest and inhale. Did you feel it?
- Now try not to breathe. Take a deep breath and hold your breath.
-What did you feel when you weren’t breathing? Were you comfortable? (Badly)
-What conclusion can be drawn?
Conclusion:
Air is necessary for breathing; a person cannot live without air.
The teacher invites the children to go to the tables with the equipment.
Experience No. 1 . Air is invisible, transparent, elastic, it can be felt and heard.
-Let's start researching. Take the package, what's in it? (it's empty)
-It can be folded several times. Look how thin he is. Now let's catch the air with the bag and hide it inside; to do this, twist the bag.
-Look, the bag is full of air, it has taken up all the space in the bag. Now let's untie the bag and let the air out of it. The package became thin again.
-Why? (He has deflated and there is no more air inside him)
— Now we have discovered the first secret of air:
Conclusion:
Air is invisible, transparent,
to see it, you need to catch it. And we were able to do it! We caught the air and locked it in a bag, and then released it.
- Catch the air in the bag again, touch it with your hands. How do you feel? (As if there is something in the bag, the bag creases when you press on it with your fingers, when you lower your fingers, it takes its shape again).
Conclusion:
air is elastic.
Air can be caught and locked where? - into a ball, sphere, tire. The trapped air softens the blow, so the tires are inflated with it; he makes the ball bounce. Compare how an inflated and an uninflated ball bounces.
- Let's make sure that there is air there. Take a stick and carefully pierce the bag. Bring it to your face and press on it. What do you feel? (The wind's blowing)
“So, if we can’t see air, what can we do?” (Feel)
Feel it like a light breeze on your face.
Take your fans and wave what you feel ( the wind)
-
What is wind?
( Wind is the movement of air)
-
Where is wind used by humans?
(in mills, on ships, a fan, a balloon, a kite, etc.)
- Air can not only be felt, but also heard. With what is this possible? ( Wind, pump, hair dryer, vacuum cleaner, etc. )
- Pick up rubber toys and press on them. Can you hear the air? Now try to pinch the hole with your finger. What's happening?
— I invite two of you who wish to play wind instruments
-What do we hear? (sounds)
-Children blow into the hole of the instrument, the air trembles and a sound is produced, sounds spread through the air. For example, on the Moon, where there is no air, you can’t hear anything, it’s useless to talk - sounds are not transmitted.
Where can we hear the air? (everywhere)
-Let's record everything that we have now learned in the table. First what did we do? What did you learn? ( Air invisible, transparent)
How did we know this?
That's right, Nastyusha paste the picture into the table. What other air? (elastic)
What helped us find out that the air is elastic? That’s right, Misha, come and fix the picture in the table.
What else have we learned? ( The air can be felt by the skin and heard).
What helped us here? This is also true, and we will paste this on the sign.
- What conclusion did we draw?
Conclusion:
The air is transparent, colorless, elastic. The air can be felt by the skin and heard.
